Coatings

From the deep UV to the long wave IR, REO possesses the industry’s most comprehensive manufacturing capabilities for thin film coatings for optics and laser applications. Our breadth of coating equipment enables REO to deliver optimal performance, volume, and value. For state of the art thin films coatings in high volume…

Thin Film Coating

Over 20 years ago, REO became the first company to commercially provide Ion Beam Sputtered (IBS) thin film coatings. Today, we have expanded our technology to produce the highest quality thin films performing a range of functions across the full optical spectrum from the deep UV (190nm) through the long wave IR (14um). With a total of 35 coating chambers in operation, REO’s ability to produce the highest performance, lowest loss, most durable thin films across the spectrum is unmatched in the world.

Ion Beam Sputtered Coatings (IBS)

REO pioneered the commercial use of IBS Coatings in the late 1980’s. With 22 IBS systems in operation today, REO is home to the world’s largest concentration of IBS optical coating technology. Our IBS technology produces thin films with exceptionally low scatter and absorption along with high mechanical and environmental durability. Utilizing primarily metal oxide materials, REO uses IBS to produce films which function from the UV through the Mid IR (up to 6um).

Thermal Evaporation

Evaporative coatings are produced in a high vacuum chamber. Both metals and dielectric coating materials can be utilized with this technique. The coating material is heated either resistively or through electron beam bombardment until it vaporizes. The vapor then streams away from the source and recondenses on all surfaces that are in a line of sight with the source. Wide range of coating materials allow coatings from the deep UV, to the LWIR.

Thin Film Engineering

REO Thin Film Engineering is the core technology of our company. Collectively, our engineering team has well over 100 years of TF manufacturing and design experience. We strive to be an extension of your own engineering and product development organization. We leverage our experience to provide you with the most efficient and robust solutions for your component and assembly requirements.

Facilities

Our factory has been built and organized for optics, thin film coatings and assembly fabrication. Clean rooms, state of the art metrology and our laminar flow production areas for contamination controls are just the foundation of what we do to ensure excellence.
